Serial No. 37454.7.

To all whom 'it may concern Be it known that 1, PAUL LIER, a citizen ofthe United States, residing at Emerson, in the county of Dixon and Stateof Ne braska, have invented a new and useful Disk Holder or Rest, ofwhich the following is a specification.

The invention relates to improvements in while sharpening the same byhammering them out on an anvil.

A further object of the invention is to provide a disk holder or rest ofthis character, adapted to support a cultivator disk in proper positionon an anvil for hammering the same, and capable of preventing a diskfrom jumping around the anvil and springing out of shape, while it isbeing operated on by either a hand or trip hammer.

Another object of the invention is to provide a disk holder, adapted toenable a cultivator and plow disk to be conveniently held with one hand,and capable of being readily removed for heating and replaced withoutdetaching or adjusting any of the parts of the device.

The invention also has for its object to provide a disk holder or rest,which will possess great strength and durability, and which will not getout of order or lose its shape.

Vith these and other objects in view, the invention consists 111 theconstruction and novel comb1nat1on of parts hereinafter fully described,illustrated in the accom panying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, Within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages ofthe invention.

In the drawing: Figure 1 is a side elevation of a disk holder or rest,constructed in accordance with this invention and shown applied to ananvil, a cultivator or plow disk being arranged in position forhammering. Fig. 2 is a vertical sectional view of the same. Fig. 3 is aperspective view of the upper port1on of the dev1ce.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

1 designates a vertically adjustable bracket, provided with a verticalstem or standard 2, having upwardly extending diverging or forked arms 3and 4, which support the top 5 of the bracket. The stem or standard 2 isarranged in upper and lower eyes 6 and 7, having threaded shanks 8 and9, which are embedded in a block 10, that supports an anvil 11. The eyes6 and 7 are vertically alined, and a clamping screw 12 is mounted on theupper eye for engaging the stem or standard 2, asclearly illustrated inFig. 2 of the drawing. A nut 13 is arranged on the shank of the uppereye, and is interposed between the former and the block to form anabutment for the upper eye.

The top 5 of the bracket consists of an inclined bar or member, which isslightly curved and which is provided at its lower i The shank, whichpierces a transverse seat bar or member 18, has its lower portionthreaded for the reception of a thumb nut 19, which clamps the pivot andthe seat bar or member at any point between the supporting arms 3 and 4.A washer is preferably interposed between the thumb nut and the lowerface of the top bar or member and the shoulder 20, formed by reducingthe shank, engages the upper face of the transverse seat bar or member.The squared portion 16 of the shank fits the slot 15, and preventsrotary movement of the pivot and the seat bar or member, which is alsoprovided with a rectangular perforation 21.

The seat bar or member 18, which extends laterally from opposite Sidesof the top bar or member of the bracket, is set at an inclination, andis curved longitudinally to conform to the curvature of a cultivator orplow disk 22, and it presents an upper concave face to the lower convexface of the disk 22. The pivot, which is inclined, projects upwardlyfrom the seat bar or member and extends through the central opening ofthe disk 22, as clearly illustrated in Fig. 2 of the drawing, and thedisk is supported at an inclination, with its lower edge resting uponthe anvil, in position to be operated on by either a hand or triphammer. The device will prevent the disk from jumping around orspringing out of shape while it is being operated on by a hammer, andthe disk may be readily removed from the device for heating, or otherpurpose without removing or adjusting any of the parts of the device.The disk is freely rotatable on the pivot to arrange any portion or itsedge on the anvil. Every blow of a hammer upon the disk jars the anviland the disk, but as the arms 1% of the disk holder rest against theanvil, the weight of the latter will carr he disk holder back to itsproper position, and to this extent the disk holder is self-acting.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. A disk holder or rest comprising a bracket provided with a top bararranged at an inclination and having a longitudinal slot, a seatconsisting of a transverse bar arranged above and supported by thetopbar of the bracket, said seat being curved and set at an inclinationat one side of an anvil in position to permit the edge of a disk to restupon the anvil, an inclined pivot having a lower threaded end andpiercing and engaging the seat and operating in the said slot to permitthe seat to be moved toward and from the anvil, and a nut arranged onthe threaded end of the pivot and located below and engaging the saidtop bar for securing the seat in its adjustment.

2. A disk holder or rest provided with a pivot for a disk and having aseat for the disk contiguous to the pivot, said disk holder or restbearing against and slidable vertically along one side of an anvil topermit the edge of the disk to rest thereon, and means for securing thedisk holder or rest to the support for the anvil, whereby the diskholder or rest is adapted to vibrate independently of the anvil.

3. A disk holder or rest comprising an inclined bracket bearing againstand slidable vertically along one side of an anvil and provided with adepending stem, a disk-receiving pivot carried by the bracket andarranged at an inclination to permit the edge of the disk to rest uponthe anvil, and means for adjustably securing the stem to the support forthe anvil to permit the bracket to vibrate independently of the anviland also to enable the bracket to be adjusted vertically to vary thebevel of the disk.

4. A disk holder or rest comprising an inclined bracket bearing againstand slidable vertically along one side of an anvil and provided with adepending stein, a disk-receiving pivot carried by the braeke; andarranged at an inclination to permit the edge of the disk to rest uponthe anvil, and means for adjustably securing the stem to the support forthe anvil to permit the bracket to vibrate independently of the anvil,said means including upper and lower eyes extending from the said anvilsupport and receiving the lower portion of the stem, and a clampingscrew carried by one of the eyes and engaging the stem.

A disl holder or rest comprising a bracket having an inclined topportion provided at the lower end with arms arranged to lit againstauanvil, and a disl-t-receiving pivot in .d on the bracket.

In testimony that l claim the .toregoing as my own, I lave heretoailixed my signature in the presence of two witnesses.
